' Application liled June 1, 1926. sensigiwo. 112,8f2r] such as coldcream and the like, to employ them frequently, and it is therefore anobject of my invention to package a limited suply of such cold cream orlike material in such a way that the same may be very easily dispensedfrom the package in an amount su cient for one application to the faceof the user and without requiring the user to withdraw such a limitedquantity as is required at the time from a larger mass of cream,

which is inconvenient, and it is likewise inconvenient to carry such alarger quantity of the material.

Another object of my invention, therefore, is to provide a new method ofvending cold cream and'like materials in limitedquantitieswithout Waste.

Other objects of my invention and the invention itself will be revealedas the description of an embodiment thereof progresses, and in whichdescription reference will be had to the accompanying drawingsillustrating the principles involved.

Referring to the drawings:

Fig. 1 shows in longitudinal medial section the packaged material to bevended;

Fig. 2 illustrates the package separated into its two telescopableparts;

Fig. 3 illustrates a preliminary step in the ejecting of cold cream fromthe reservoir 1 of the containing parts of Fig. 2;

Fig. 4: illustrates a subsequent stage in the operation;

Fig. 5 illustrates'a succeeding stage and Fig.6 illustrates the ultimatestage in the operation; v

Fig. 7 illustrates a stage. of improper operation which would be securedwere it not for certain provisions, hereinafter set forth, had in theenjoyment of my invention; and

Figs. 8 and 9 illustrate subsequent stages in the operation which wouldbe secured if the invention were attempted to be practiced .nection withFig. 7.

under'the improper conditions hereinafter set forth and referred tohereinabove in con- In the practice of my invention, I employ a capsulecomprising two parts, one of the parts illustrated at 1 being a coldcream reservoir and a second part 2 being a cap ada ted to be telescopedover the mouth of t e reservoir part to close the same, as illustratedin Fig. 1. Both the reservoir and the cap are generally in cylindricalform with rounded ends and circular months. The diameter of thecylindrical portion of the capis sufficiently reater than thediameter ofthe cylindrical portion of the reser-v voir, so that the cap may betelescoped over the exterior of the reservoir but making a snug fittingcontact therewith. The capsule reservoir portion 1 is preferably made ofgelatin material; the cap 2 may likewise be made of gelatin material butit may also be made of other materials, such as celluloid and the like.

In the practice of my improved method, I first provide an emulsion ofcold cream material constituents comprising an oil and water, the amountof oil and water being preferably such as to secure good cleanslngqualities, and at the same time the amount of water in the material ismade sufficient in quantity that coming in contact with the gelatinmaterial 1, in about a weeks time, it will so soften the gelatinmaterial that the container 1 having a rounded dome shaped end 3 ma betaken between the fingers of one han as illustrated in Fig. 3, and uponpressure being exerted by the fingers toward each other, the containerwill be deformed, as illustrated in Figs. 4, 5 and 6, successively, Fig.6 representing a stage 9 wherein the capsule will be entirely flattenedout.

In Figs. 7 8 and 9, I have illustrated what takes place in a capsule ofthe ordinary gelatin type when filled with a cream material notcontaining an emulsion comprising Water, or wherein the water has notbeen permitted to soften the capsule to permit its dome portion 3 to beflattened by a pressure .exerted by the fingers of one hand, or

wherein a container of other material than gelatin, such as a celluloidcontainer, is employed. In all such latter cases, it is practicallyimpossible with the amount of pressure 'which could conveniently beexerted by a person of ordinary strength to flatten containersheretofore in common use in order to dispense substantially the entirecontents of the container. The dome 3 being an arch, is required to besoftened to make it pliable, in order that it may be crushed orflattened, as illustrated in Fig. 6, and only under such flatteningconditions may the contents of the container be ejected economically,since otherwise there will always reside in the container a majorportion of the cold cream material.

By so packaging the cold cream material, users may carry one or more ofthe capsules with them in a purse, vanity case, pocket, or the like, andafter expressing the contents, can throw away the container, it beinginexpensive and purchasably filled with cold cream at small cost.

After packaging the cold cream material, as illustrated in Fig. 1, Ipreferably dip the capsule, after closing it, into an oil, which willenter between the contacting surfaces of the capsule end 2 and thecapsule end 1 and seal the interior of the capsule and prevent itsmoisture content from being changed by leakage through the joint formedby the contacting portions of the two telescoped capsule parts. Thecapsules are then ready for marketing, and I may enclo'se each of'themin a wrapper of non-absorbent material, such as waxed paper, cellophineor the like.

In order to. prevent an undue softening of the capsule material when thecold cream material packaged comprises such an amount of water as wouldotherwise unduly soften the capsule, sometimes I previously expose thecapsule to the fumes of formaldehyde. I find that when this is done thatthe capsule is made more or less non-absorbent, depending upon theamount of ex osure to the fumes, and by predetermining t e amount ofexposure a predetermined amount of softening may be accomplished.

Having thus described my invention in this specific embodiment, I amaware that the same may be embodied in containers of different materialsand form, and for vending substances, departing from that hereinspecifically described but all Without departing from the spirit of myinvention.

I claim:

A container adapted to hold cold cream comprising an emulsion of oil andWater, comprising a pair of gelatin capsule cups, one of which has adome-shaped closed end, both having open ends, the open end of one ofthe cups being of less diameter than that of the other cup and adaptedto be telescoped therein, the walls of the container adapted to be actedupon by the Water in the emulsion to soften the same, the outer surfaceof the Walls being rendered hard and relatively non-absorbent of water.

' In testimony whereof I hereunto afiix my signature this 6th day ofMay, 1926.
